The highway system of the United States is a network of interconnected state, U.S., and Interstate highways. Each of the fifty states, the District of Columbia, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands, and the U.S. Virgin Islands own and maintain a part of this vast system, including U.S. and Interstate highways, which are not owned or maintained at the federal level.
Interstate Highways have the highest speed limits and the highest traffic numbers. Interstates are numbered in a grid: even-numbered routes for east–west routes (with the lowest numbers along Mexico and the Gulf of Mexico), and odd-numbered routes are north–south routes (with the lowest numbers along the Pacific Ocean). Three-digit Interstates are, generally, either beltways or spurs of their parent Interstates (for example, Interstate 510 is a spur into the city of New Orleans, Louisiana, and is connected to Interstate 10).
U.S. Numbered Highways are the original interstate highways, dating back to 1926. U.S. Highways are also numbered in a grid: even numbered for east–west routes (with the lowest numbers along Canada) and odd numbered for north–south routes (with the lowest numbers along the Atlantic Ocean). Three-digit highways, also known as "child routes," are branches off their main one- or two-digit "parents" (for example, U.S. Route 202 is a branch of U.S. Route 2). However, US 101, rather than a "child" of US 1, is considered a "mainline" U.S. Route.
State highways are the next level in the hierarchy. Each state and territory has its own system for numbering highways, some more systematic than others. Each state also has its own design for its highway markers; the number in a circle is the default sign, but many choose a different design connected to the state, such as an outline of the state with the number inside. Many states also operate a system of county highways.
Scenic byways can be designated over any classification of road in the United States. There are the National Scenic Byways, National Forest Scenic Byways and Bureau of Land Management Back Country Byways at the national level. Most states have their own system for designating byways, some more systematic than others. Native American tribes may designate byways as well.

Interstate 70 (I-70) is a transcontinental Interstate Highway in the United States, stretching from Cove Fort, Utah, to Baltimore, Maryland. In Colorado, the highway traverses an east–west route across the center of the state. In western Colorado, the highway connects the metropolitan areas of Grand Junction and Denver via a route through the Rocky Mountains. In eastern Colorado, the highway crosses the Great Plains, connecting Denver with metropolitan areas in Kansas and Missouri. Bicycles and other non-motorized vehicles, normally prohibited on Interstate Highways, are allowed on those stretches of I-70 in the Rockies where no other through route exists.
The United States Department of Transportation (USDOT) lists the construction of I-70 among the engineering marvels undertaken in the Interstate Highway System and cites four major accomplishments: the section through the Dakota Hogback, Eisenhower Tunnel, Vail Pass, and Glenwood Canyon. The Eisenhower Tunnel, with a maximum elevation of 11,158 feet (3,401 m) and length of 1.7 miles (2.7 km), is the longest mountain tunnel and highest point along the Interstate Highway System. The portion through Glenwood Canyon was completed on October 14, 1992. This was one of the final pieces of the Interstate Highway System to open to traffic and is one of the most expensive rural highways per mile built in the country. The Colorado Department of Transportation (CDOT) earned the 1993 Outstanding Civil Engineering Achievement Award from the American Society of Civil Engineers for the completion of I-70 through the canyon.

The Ridge Route, officially the Castaic–Tejon Route and colloquially known as the Grapevine, was a two-lane highway between Los Angeles County and Kern County, California, United States. Opened in 1915 and paved with concrete between 1917 and 1921, the road was the first paved highway directly linking the Los Angeles Basin with the San Joaquin Valley (southern Central Valley) over the Tejon Pass and the rugged Sierra Pelona Mountains ridge south of Gorman. Much of the old road runs through the Angeles National Forest, and passes many historical landmarks, including the National Forest Inn, Reservoir Summit, Kelly's Half Way Inn, Tumble Inn, and Sandberg's Summit Hotel. North of the forest, the Ridge Route passed through Deadman's Curve before ending at Grapevine.
The road was originally built as a state highway, a segment of the unsigned Legislative Route 4, before it became signed as part of U.S. Route 99 (US 99) in 1926. The road was then bypassed by the three-lane Ridge Route Alternate to handle increased traffic and remove curves; the Alternate in Los Angeles County was completed in 1933, and Kern County line to Grapevine in 1936. The roadway was widened to a four-lane expressway in 1953 and replaced by an eight-lane freeway, Interstate 5 (I-5) in 1960-70. The portion of the road in the Angeles National Forest was added to the National Register of Historic Places in 1997, by the efforts of retired engineer Harrison Scott. Much of the road has been closed by the U.S. Forest Service; other remnants are used by local traffic. (Full article...)- State Route 94 (SR 94) is a state highway in the U.S. state of California that is 63.324 miles (101.910 km) long. The western portion, known as the Martin Luther King Jr. Freeway, begins at Interstate 5 (I-5) in downtown San Diego and continues to the end of the freeway portion past SR 125 in Spring Valley. The non-freeway segment of SR 94 that continues east through the mountains to I-8 near Boulevard is known as Campo Road.
The Campo road served as a wagon road providing access to eastern San Diego County as well as Imperial County. The road was added to the state highway system in 1933, and signs for Route 94 were posted along local roads later that decade. Efforts to convert the western half of the route to a freeway got underway in the 1950s, and the freeway was complete by 1962 west of the road that became SR 125. Construction continued east to Avocado Road over the next few years. Various proposals for widening the highway have come from the California Department of Transportation (Caltrans), but local opposition resulted in the delay or cancellation of many of these proposals. (Full article...) - Interstate 69 (I-69) is a part of the Interstate Highway System that will eventually run from the Mexican border in Texas to the Canadian border at Port Huron, Michigan. In Michigan, it is a state trunkline highway that enters the state south of Coldwater and passes the cities of Lansing and Flint in the Lower Peninsula. A north–south freeway from the Indiana–Michigan border to the Lansing area, it changes direction to east–west after running concurrently with I-96. The freeway continues to Port Huron before terminating in the middle of the twin-span Blue Water Bridge while running concurrently with I-94 at the border. There are four related business loops for I-69 in the state, connecting the freeway to adjacent cities.
Predecessors to I-69 include the first M-29, US Highway 27 (US 27), M-78 and M-21. The freeway was not included on the original Interstate Highway System planning maps in the mid-1950s, but it was added in 1958 along a shorter route. Michigan built segments of freeway for the future Interstate in the 1960s, and the state was granted additional Interstate mileage in 1968 to extend I-69 north and east to Flint. Later extensions in 1973 and 1987 resulted in the modern-day highway. The first freeway segment designated as I-69 in Michigan opened in 1967, and the last was completed in 1992, finishing Michigan's Interstate System. US 27 previously ran concurrently with I-69 from the Indiana–Michigan state line north to the Lansing area, but this designation was removed in 2002. (Full article...) - Interstate 80 (I-80) is a transcontinental Interstate Highway in the United States, stretching from San Francisco, California, to Teaneck, New Jersey. In Iowa, the highway travels west to east through the center of the state. It enters the state at the Missouri River in Council Bluffs and heads east through the southern Iowa drift plain. In the Des Moines metropolitan area, I-80 meets up with I-35 and the two routes bypass Des Moines together. On the northern side of Des Moines, the Interstates split and I-80 continues east. In eastern Iowa, it provides access to the University of Iowa in Iowa City. Northwest of the Quad Cities in Walcott is Iowa 80, the world's largest truck stop. I-80 passes along the northern edge of Davenport and Bettendorf and leaves Iowa via the Fred Schwengel Memorial Bridge over the Mississippi River into Illinois.
Before I-80 was planned, the route between Council Bluffs and Davenport, which passed through Des Moines, was vital to the state. Two competing auto trails, the Great White Way and the River-to-River Road, sought to be the best path to connect three of the state's major population centers. The two trails combined in the 1920s and eventually became US Highway 32 (US 32) in 1926. US 6, which had taken the place of US 32, became the busiest highway in the state. In the early 1950s, plans were drawn up for the construction of an Iowa Turnpike, to be the first modern four-lane highway in the state, along the US 6 corridor. Plans for the turnpike were shelved when the Interstate Highway System was created in 1956. (Full article...) - New York State Route 308 (NY 308) is a short state highway, 6.19 miles (9.96 km) in length, located entirely in northern Dutchess County, in the U.S. state of New York. It is a major collector road through a mostly rural area, serving primarily as a shortcut for traffic from the two main north–south routes in the area, U.S. Route 9 (US 9) and NY 9G, to get to NY 199 and the Taconic State Parkway. The western end of NY 308 is located within Rhinebeck's historic district, a 2.6-square-mile (6.7 km2) historic district comprising 272 historical structures. The highway passes near the Dutchess County Fairgrounds, several historical landmarks, and briefly parallels the Landsman Kill.
Artifacts found near Lake Sepasco, near NY 308's eastern terminus at Rock City, date to about 1685, when the Sepasco Native Americans built the Sepasco Trail from the Hudson River, eastward through modern-day Rhinebeck (then Sepasco or Sepascoot) to the lake, following roughly NY 308 and its side roads. The trail remained until 1802, when part of the Ulster and Delaware Turnpike—also known as the Salisbury Turnpike—was chartered over the trail and extended from Salisbury, Connecticut, to the Susquehanna River at or near the Town of Jericho (now Bainbridge). (Full article...) - State Route 522 (SR 522) is a state highway in the U.S. state of Washington that serves the Seattle metropolitan area. Approximately 25 miles (40 km) long, it connects the city of Seattle to the northeastern suburbs of Kenmore, Bothell, Woodinville, and Monroe. Its western half is primarily an arterial street, named Lake City Way and Bothell Way, that follows the northern shore of Lake Washington; the eastern half is a grade-separated freeway that runs between Woodinville and Monroe. SR 522 connects several of the metropolitan area's major highways, including Interstate 5 (I-5), I-405, SR 9, and U.S. Route 2 (US 2).
The present-day route of SR 522 was built in stages between 1907 and 1965, beginning with the Red Brick Road from Seattle to Bothell, then part of the Pacific Highway and later US 99. The road later became a branch of Primary State Highway 2 (PSH 2) in 1937, and was extended east to Redmond and North Bend. A branch of the Stevens Pass Highway was built to connect PSH 2 in Bothell and Monroe in 1965, and was incorporated into SR 202 after it was designated in 1964. The Bothell–Monroe highway was re-designated as part of SR 522 in 1970, leaving SR 202 on the Bothell–North Bend highway. (Full article...) - U.S. Route 101, or U.S. Highway 101 (US 101), is a major north–south highway that traverses the states of California, Oregon, and Washington on the West Coast of the United States. It is part of the United States Numbered Highway System and runs for over 1,500 miles (2,400 km) along the Pacific Ocean. The highway is also known by various names, including El Camino Real in parts of California, the Oregon Coast Highway, and the Olympic Highway in Washington. Despite its three-digit number, normally used for spur routes, US 101 is classified as a primary route with 10 as its "first digit".
The highway's southern terminus is at a major interchange with Interstate 5 (I-5) and I-10 in Los Angeles. US 101 follows several freeways in Southern California as it travels north of the Santa Monica Mountains and along the coast, where it is concurrent with California State Route 1 (SR 1). The highway travels inland from the coast after it splits from SR 1 and approaches the San Francisco Bay Area, where it becomes the Bayshore Freeway and later traverses San Francisco on city streets to reach the Golden Gate Bridge. US 101 continues north on the Redwood Highway and rejoins the coast before it enters Oregon. (Full article...) - New York State Route 319 (NY 319) was a state highway in Chenango County, New York, in the United States. It was 5.47 miles (8.80 km) long and connected the hamlet of Preston to the nearby city of Norwich. The route began in the hamlet at an intersection with three county-maintained highways and proceeded eastward through the town of Preston to downtown Norwich, where it terminated at an intersection with NY 12.
What became NY 319 was originally built during the early 19th century as the Norwich and Preston Turnpike, one of many privately maintained turnpikes in the state of New York. The state of New York assumed ownership of the turnpike's routing in the early 20th century, and the Preston–Norwich state highway was designated as NY 319 as part of the 1930 renumbering of state highways in New York. Maintenance of NY 319 was split between the state and the city of Norwich, with the New York State Department of Transportation (NYSDOT) handling the part of the route west of the city limits. (Full article...) - State Route 67 (SR 67) is a state highway in San Diego County, California, United States. It begins at Interstate 8 (I-8) in El Cajon and continues to Lakeside as the San Vicente Freeway before becoming an undivided highway through the eastern part of Poway. In the town of Ramona, the route turns into Main Street before ending at SR 78. SR 67 provides direct access from the city of San Diego to the East County region of San Diego County, including Ramona and Julian.
The route has existed as a railroad corridor since the turn of the 20th century. A highway known as the Julian road was built by 1913, and was designated as Legislative Route 198 in the state highway system by 1935. Route 198 was renumbered SR 67 in the 1964 state highway renumbering. A freeway south of Lakeside was built in the late 1960s, and opened to traffic in 1970. Since then, the portion of the highway north of Lakeside has become known for a high number of traffic accidents and related fatalities. The California Department of Transportation (Caltrans) has made several attempts to remedy the problem and make the road safer. (Full article...) - US Highway 23 (US 23) is a north–south United States Numbered Highway that runs from Jacksonville, Florida, to Mackinaw City, Michigan. In the state of Michigan, it is a major, 362-mile-long (583 km), north–south state trunkline highway that runs through the Lower Peninsula. The trunkline is a freeway from the Michigan–Ohio state line near Lambertville to the city of Standish, and it follows the Lake Huron shoreline from there to its northern terminus. Serving the cities of Ann Arbor and Flint, US 23 acts as a freeway bypass of the Metro Detroit area. Overall, the highway runs through rural areas of the state dominated by farm fields or woodlands; some segments are urban in character in the Ann Arbor, Flint and Tri-Cities areas. The section from Flint north to Standish also carries Interstate 75 (I-75) along a concurrency that includes a segment that carries almost 70,000 vehicles on a daily basis.
The first transportation routes along what is now US 23 in the state were sections of two Indian trails. In the early 20th century, four different auto trail names were applied to roads now a part of the highway. These roads were included as part of two state highways in the initial state highway system in 1919. When the United States Numbered Highway System was first designated on November 11, 1926, the new US 23 replaced the other designations along its route. Since creation, the road has been moved and realigned several times. Through the 1930s and 1940s, the lakeshore routing was created to replace a path that ran further inland through the northern portion of the state. Starting in the early 1950s, various sections in the southeastern and central areas of the Lower Peninsula were upgraded to freeways, bypassing several major cities in the area. These improvements were completed by the end of the 1960s. Since then a new crossing of the Saginaw River at Zilwaukee was built to replace a drawbridge that carried the I-75/US 23 freeway over a shipping channel. (Full article...) - New York State Route 32 (NY 32) is a north–south state highway that extends for 176.73 miles (284.42 km) through the Hudson Valley and Capital District regions of the U.S. state of New York. It is a two-lane surface road for nearly its entire length, with few divided sections. From Harriman to Albany, it is closely parallel to Interstate 87 (I-87) and U.S. Route 9W (US 9W), overlapping with the latter in several places.
NY 32 begins at NY 17 on the outskirts of the New York metropolitan area in Woodbury just outside Harriman, and ends at NY 196 east of Hudson Falls just south of the Adirondacks. In between, the road passes through the cities of Newburgh, Kingston, Albany, Cohoes, and Glens Falls. Outside of the cities, it offers views of the Hudson Highlands, Shawangunk Ridge, Catskill Mountains, and, during an overlap with US 4 north of Albany, the Hudson River. (Full article...) - U.S. Route 50 (US 50) is a transcontinental highway in the United States, stretching from West Sacramento, California, in the west to Ocean City, Maryland, on the east coast. The Nevada portion crosses the center of the state and was named "The Loneliest Road in America" by Life magazine in July 1986. The name was intended as a pejorative, but Nevada officials seized it as a marketing slogan. The name originates from large desolate areas traversed by the route, with few or no signs of civilization. The highway crosses several large desert valleys separated by numerous mountain ranges towering over the valley floors, in what is known as the Basin and Range province of the Great Basin.
US 50 has a diverse route through the state, traversing the resort communities of Lake Tahoe, the state capital in Carson City, historical sites such as Fort Churchill State Historic Park, petroglyphs, alpine forests, desert valleys, ghost towns, and Great Basin National Park. (Full article...) - Interstate 80 Business (I-80 Bus.) is an unofficial business loop of Interstate 80 (I-80) that is 2.26 miles (3.64 km) long and serves as the main street for the US cities of West Wendover, Nevada, and Wendover, Utah, along a roadway named Wendover Boulevard. Wendover Boulevard was originally part of US Route 40 (US 40), which connected California to New Jersey via Nevada and Utah. A portion of the Nevada segment runs concurrently with US 93 Alternate (US 93 Alt.), and the entire portion in Utah is coterminous with State Route 58 (SR-58). The Nevada Department of Transportation (NDOT) applied for the business loop designation in the early 1980s, but the designation has never been approved; nevertheless, signs are posted in both states. Between July 1976 and 1993, I-80 Bus was concurrent with State Route 224 (SR 224) in Nevada. (Full article...)
- Interstate 696 (I-696) is an east–west auxiliary Interstate Highway in the Metro Detroit region of the US state of Michigan. The state trunkline highway is also known as the Walter P. Reuther Freeway, named for the prominent auto industry union head by the Michigan Legislature in 1971. I-696 is a bypass route, detouring around the city of Detroit through the city's northern suburbs in Oakland and Macomb counties. It starts by branching off I-96 and I-275 at its western terminus in Farmington Hills, and runs through suburbs including Southfield, Royal Oak and Warren before merging into I-94 at St. Clair Shores on the east end. It has eight lanes for most of its length and is approximately 10 miles (16 km) north of downtown Detroit. I-696 connects to other freeways such as I-75 (Chrysler Freeway) and M-10 (Lodge Freeway). Local residents sometimes refer to I-696 as "The Autobahn of Detroit".
Planning for the freeway started in the 1950s. Michigan state officials proposed the designation I-98, but this was not approved. Construction started on the first segment in 1961, and the Lodge Freeway was designated Business Spur Interstate 696 (BS I-696) the following year. The western third of the freeway opened in 1963, and the eastern third was completed in January 1979. The central segment was the subject of much controversy during the 1960s and 1970s. Various municipalities along this stretch argued over the routing of the freeway such that the governor locked several officials into a room overnight until they would agree to a routing. Later, various groups used federal environmental regulations to force changes to the freeway. The Orthodox Jewish community in Oak Park was concerned about pedestrian access across the freeway; I-696 was built with a set of parks on overpasses to accommodate their needs. The Detroit Zoo and the City of Detroit also fought components of the freeway design. These concessions delayed the completion of I-696 until December 15, 1989. Since completion, the speed limit was raised from 55 to 70 miles per hour (89 to 113 km/h). In addition, some interchanges were reconfigured in 2006. (Full article...)

- K-34 is a 29.26-mile-long (47.09 km) state highway in southwestern Kansas that runs from U.S. Route 160 (US-160) and US-183 near Ashland to US-400 near Bucklin. It is one of the lesser-traveled highways in the state and is not part of the National Highway System. It is a two-lane road for its entire length.
K-34 was originally designated in southeastern Kansas, running through Neodesha. The designation was moved to southwestern Kansas in 1937, replacing the old K-41 designation. The highway formerly ran to the Oklahoma border via a concurrency with US-183. The designation was shortened in 1993 to its current routing. (Full article...) - New York State Route 31E (NY 31E) is a 5.29-mile (8.51 km) state highway located in western New York in the United States. It serves as a northerly alternate route of NY 31 between the village of Middleport in eastern Niagara County and the nearby village of Medina in Orleans County. NY 31E connects to NY 31 at each end by way of a short overlap with NY 271 in Middleport. Most of NY 31E parallels the Erie Canal, and parts of the route run adjacent to the waterway. Outside of the two villages at each end, NY 31E traverses mostly rural areas of the towns of Royalton and Ridgeway.
The origins of the route date back to 1914 when its routing was included as part of a spur route of Route 30, a cross-state, unsigned legislative route. The spur route was eliminated in 1921, and the road went unnumbered until 1930 renumbering of state highways in New York when it became part of NY 3. Most of NY 3 west of Rochester was replaced by NY 31 in the mid-1930s, and NY 31 was realigned onto its present, more southerly alignment between Middleport and Medina in 1949. Its former canalside alignment became NY 31E at this time. Most of NY 31E is maintained by the New York State Department of Transportation (NYSDOT); however, two sections in Niagara County and Medina are locally maintained. (Full article...) - U.S. Route 67 (US 67) is a component of the United States Numbered Highway System that connects Presidio, Texas, to Sabula, Iowa. In Illinois, it serves the western region of the state known as Forgottonia, named for the lack of regional transportation and infrastructure projects. The highway begins its path through the state by crossing the Clark Bridge over the Mississippi River from Missouri at Alton and heads northward through Jerseyville and Jacksonville before it crosses the Illinois River at Beardstown. The northern half of the route serves Macomb and Monmouth before it enters the Quad Cities. It leaves the state at Rock Island by crossing the Rock Island Centennial Bridge over the Mississippi River into Davenport, Iowa.
The roads that would become US 67 were once a part of the Burlington Way and Alton–Jacksonville Air Line auto trails from the 1910s through the end of the 1920s. In 1918, Illinois voters approved a 48-route state highway system. Among the new routes was Route 3, which connected Morrison and Chester by way of the Quad Cities, Monmouth, Beardstown, Jacksonville, Alton, and East St. Louis. US 67 was created in 1926, but it did not extend into Illinois until 1931. That year, US 67 signs were applied to Route 3 from Alton to Rock Island. In 1952, the highway was rerouted between Medora and Murrayville; an alternate route was applied to the former routing until 1964, when the alternate was renumbered Illinois Route 267 (IL 267). Since the 1980s, a group called Corridor 67 has taken up the cause of advocating the widening of US 67 to a four-lane highway for the majority of its length. Widening the highway has been a popular project among politicians stumping in western Illinois. Although some piecemeal projects have taken place, a large percentage of the highway has not seen any upgrades despite there being other projects. (Full article...) - Interstate 405 (I-405), also known as the Stadium Freeway No. 61, is a short north–south Interstate Highway in Portland, Oregon. It forms a loop that travels around the west side of Downtown Portland, between two junctions with I-5 on the Willamette River near the Marquam Bridge to the south and Fremont Bridge to the north.
The Stadium Freeway was envisioned in the 1940s and 1950s by the state government and was added to the Interstate Highway system in 1958. Construction began in 1963, utilizing a trench with extensive landscaping and frequent overpasses, and was the most expensive freeway project in state history at a cost of $121 million. Hundreds of buildings were demolished to make way for the freeway, which displaced approximately 1,100 households. (Full article...) - M-130 was the designation of a former state trunkline highway in the southeastern corner of the US state of Michigan. It ran from a junction with US Highway 23/M-50 (US 23/M-50) northward across the River Raisin and then turned southeasterly along North Custer Road on the north side of the river to Monroe. The highway designation was commissioned in 1929 and used until 1955. M-130 had a spur route that was created in 1938 and lasted until the main highway was removed from the state highway system. Both highways are now under local control. (Full article...)
- Route 144 is a 2.956-mile-long (4.757 km) state route in Ste. Genevieve County, Missouri. Its western terminus is at Route 32 near the village of Millers. The route travels southeastward toward Hawn State Park. The road then turns east and ends at Bauer Road and Park Drive, inside the state park. The route was designated in 1972 and has kept the same alignment since. (Full article...)
- M-17 is a 6.390-mile-long (10.284 km) state trunkline highway in the U.S. state of Michigan, connecting the cities of Ypsilanti and Ann Arbor in Washtenaw County. It was once part of a highway that spanned the southern Lower Peninsula of Michigan before the creation of the U.S. Highway System in 1926. The designation once extended into downtown Detroit, but the eastern terminus was progressively scaled back in the late 1960s to the current location in Ypsilanti. The changes made to the highways in Washtenaw County spawned Business M-17 (Bus. M-17), a business loop for 11 years between 1945 and 1956. (Full article...)
- U.S. Route 101 (US 101) is a north–south United States Numbered Highway that runs between Los Angeles, California, and Tumwater, Washington. U.S. Route 101 in California covers approximately 808 miles (1,300 km) between the East Los Angeles Interchange and the Oregon border, making it the longest numbered route in California's highway network.
US 101 is a critical freeway in Greater Los Angeles and the San Francisco Bay Area; it is also a communal highway in the Central and North coasts, where it connects cities such as Santa Barbara, San Luis Obispo, Salinas, and Eureka. The Los Angeles portion of US 101 is one of the most congested freeways in the U.S. based on multiple studies. In the Central Coast, US 101 is a mix of freeway and expressway, while the North Coast segment is mostly a two-lane road with pockets of controlled-access configurations. The majority of the route is maintained by the California Department of Transportation (Caltrans). (Full article...) 
State Route 121 (SR 121) is a state highway located entirely in Thurston County, Washington, United States. The highway serves Millersylvania State Park, forming a 7.67-mile (12.34 km) loop between two interchanges with Interstate 5 (I-5) near Maytown. It is an auxiliary route of U.S. Route 12 (US 12).
The highway follows roads constructed in the early 20th century and maintained by the Thurston County government until their incorporation into the state highway system. The state government created Secondary State Highway 1M (SSH 1M) in 1937, initially connecting Rochester to Tumwater before its north end was truncated to Maytown in 1959. SSH 1M was renumbered in 1964 to the short-lived SR 801, which was then replaced by SR 121 in 1967. The Rochester–Maytown section of SR 121 was replaced by the route through Millersylvania State Park in 1991, severing its connection to US 12. (Full article...)- Mississippi Highway 555 (MS 555) is a state highway in southwestern Mississippi. The route has two sections, both in Adams County. The first section starts at Ogden Road and travels northwestward to its terminus at US 61. The second section starts at the concurrency of MS 930 and MS 932 and the concurrency of US 61 and US 84 in Natchez. MS 555 travels northward through Pine Ridge and ends at Anna's Bottom Road near the Anna site. The route travels by a few historical locations, including the Pine Ridge Presbyterian Church.

The highway runs 42.822 miles (68.915 km) from MT 41 in Twin Bridges east to U.S. Route 287 (US 287) in Ennis. MT 287 is the primary east–west highway of Madison County. The highway connects the county's four towns, including Sheridan and the county seat of Virginia City. The course of MT 287 follows the ultimate portions of two trails that met in Virginia City, the center of the Alder Gulch gold rush of the mid-1860s and the second territorial capital of Montana. Parts of the highway were improved from rudimentary roads around 1920 from Virginia City to Ennis. This connection became the first portion of Montana Highway 34 in the early 1930s; the highway was extended west to Twin Bridges in the late 1930s. MT 34 was reconstructed from Twin Bridges through Alder to Virginia City in the late 1930s and early 1940s and between Virginia City and Ennis in the late 1940s to mid-1950s. The MT 287 designation was first applied to a cross-state route from West Yellowstone to Canada in the late 1950s. The highway was rerouted in place of MT 34 in the early 1960s. MT 287 was replaced by US 287 along much of the cross-state corridor in the mid-1960s. The highway extended north of Twin Bridges to Whitehall until the late 1970s, when it achieved its current length. (Full article...)
- State Route 276 (SR 276) was a legislated, but not constructed, state highway located in the U.S. state of Washington. The highway was meant to serve as a northern bypass of Pullman in Whitman County, traveling east from U.S. Route 195 (US 195) west of the city to SR 270 east of the city. Proposals were first drawn in 1969 for a complete ring road around Pullman, with the west side built and signed as US 195 in 1975. The northern segment of the ring road was codified in law in 1973 as SR 276, but was never constructed. In 2016, the highway was removed by the state legislature. (Full article...)

- New York State Route 318 (NY 318) is an east–west state highway in the Finger Lakes region of New York in the United States. The western terminus of the route is at an intersection with NY 14 at New York State Thruway (Interstate 90 or I-90) exit 42 in the town of Phelps.

It was mostly designated as Route 6-a, an unsigned legislative route, by the New York State Legislature in 1911. The section of Route 6-a from West Junius to Halsey Corners was designated as New York State Route 291 (west of Magee) and part of NY 89 (east of Magee) as part of the 1930 renumbering of state highways in New York. NY 291 was removed in the 1940s. (Full article...) - Mississippi Highway 41 (MS 41) is a state highway in northeastern Mississippi.
